Heavyweight:-Kyotaro Fujimoto (19-1): WBO #7 / WBC #20A heavyweight Japanese fighter is something very rare, let along being ranked in the top 10. The former K-1 champion debuted in 2011 and has had a successful run in the regional scene, currently holding the OPBF & WBO Asia Pacific Heavyweight belts while riding on a 14 fight winning streak. Even though we may never see him challenging for a world title, it’s fun knowing he is there.Super Welterweight/Jr Middleweight:-Takeshi Inoue (13-0): WBO #5 / WBA #13 / WBC #19The undefeated 4-year veteran is climbing the Super Welterweight rankings very fast, managing to place himself as the #5 in the WBO. A former Japanese title holder and now the unified OPBF & WBO Asia Pacific champion, may very well be one or two fights away from his first world title opportunity.Super Lightweight/Jr Welterweight:-Hiroki Okada (18-0): WBO #3 / WBA #4 / WBC #9One of brightest prospects in Japan right now, Okada has never lost a single bout in his entire career. A bona fide knock out artist (13 KOs), he held the Japanese crown for 32 months and defended it 6 times, before winning the WBO Asia Pacific championship from Jason Pagara (41-3) this past December. Since the WBO world champion Maurice Hooker will not participate in the WBSS, this title will probably be his main focus as of now. Okada’s next confirmed appearance is on September 14th in the US (opponent TBA).

Lightweight:-Masayoshi Nakatani (17-0): WBC #7, WBO #13Much like Okada and Takuma, Nakatani is also another undefeated fighter, who just recently made a record 10th title defense of the OPBF Lightweight championship. Despite the fact that he is ranked “only” #7 by the WBC, it’s worth pointing out that his last bout took place on July 29, so that win wasn’t taken into consideration at the latest ranking updates. -Nihito Arakawa (31-6): WBO #3Former Japanese, OPBF and reigning WBO Asia Pacific Lightweight champion, Arakawa has been in many big fights through out his 14-year career. At 36, he is still looking for his second world title opportunity. Super Featherweight/Jr Lightweight:-Masaru Sueyoshi (18-1): WBO #7The 27 year old is steadily making his mark in Japan, suffering only one loss in his 4th pro bout, Sueyoshi has been victorious in his last 15 outings and even won the Japanese title on October of 2017. Another successful year and we might see him challenge for a world title by the end of 2019/beginning of 2020. Featherweight:-Satoshi Shimizu (6-0): WBC #6The Bronze Medalist at the 2012 Olympics, made his pro debut on September of 2016 and he has KOed/TKOed every single one of his opponents since then, claiming the OPBF Featherweight crown in just his 4th fight. He will defend that belt against Shingo Kawamura (16-3) later this month. If he can pass that test too, a fight with Gary Russell Jr. for the WBC title could be up for debate.-Shun Kubo (13-1): WBA #7The former WBA Super Bantamweight world champion returned this April, after his TKO loss to Daniel Roman in 2017, and won his comeback fight against former OPBF Featherweight champion & world title challenger Hiroshige Osawa (33-5)making a huge impact on his Featherweight debut.Super Bantamweight/r Featherweight:-Tomoki Kameda (35-2): WBA #2 / WBC #4 / WBO #9El Mexicanito, has been on a 4-fight winning streak since moving up a weight class and has already broke the top 5 in both the WBA & the WBC. A fight with Emanuel Navarrete (WBA #1) could potentially set up a world title fight in 2019 with the winner of Daniel Roman/Gavin McDonnell, which takes place this October.-Hidenori Otake (31-2): WBO #6 / WBC #8The reigning OPBF champion is scheduled to take on Isaac Dogboe (19-0) for the WBO World Super Bantamweight title on August 25.

Bantamweight:-Takuma Inoue (11-0): WBO #8 / WBC #9The undefeated former OPBF Super Flyweight champion is set to face reigning OPBF Bantamweight champion Mark John Yap (29-12), in a WBC World title eliminator fight on September 11. -Hiroaki Teshigawara (17-2): WBO #6Teshigawara recently stopped former world title contender Teiru Kinoshita (26-3) to defend his WBO Asia Pacific crown, bringing him one step closer to a WBO world championship match.

-Ryo Akaho (32-2): WBO #13This is more of an honorable mention as Akaho made his return to the ring this past July, since his forced retirement last year, and knocked out Robert Udtohan, thus making it in the WBO world rankings once more.Super Flyweight/Jr Bantamweight:-Kazuto Ioka (22-1): WBA #2In what must be considered the most bizarre ranking of this list, the former 3 division world champion, who’s return to the ring was announced just a couple of weeks ago,is already ranked #2 by the WBA !Ioka is scheduled to fight WBC Silver champion and 2-time world title contender McWilliams Arroyo (17-3) on September 8, in the States.-Koki Eto (22-4): WBC #5 / WBO #7 / WBA #9The former interim WBA World Flyweight champion is currently ranked in the top 10 of the WBA, the WBC and the WBO. He fights Delfin de Asis (9-5) on August 16.-Ryuichi Funai (30-7): WBO #5 / WBC #10 / WBA #13Funai knocked out Philippino standout and world title challenger Warlito Parrenas (26-8), in impressive fashion, this past June, and won the vacant WBO Asia Pacific title. A strong first title defense and Funai could be challenging for the world championship by 2019.

Flyweight:-Kosei Tanaka (11-0): WBO #1 / WBC #2Arguably one of the best fighters that have come out of Japan, Tanaka has won 2 world titles in 2 different divisions within 5 years. Now he looks to add a 3rd one to his collection as he goes one on one with Sho Kimura (17-1) for the WBO World Flyweight championship on September 24.-Masayuki Kuroda (30-7): WBA #1 / WBC #4 / WBO #5The current Japanese Flyweight champion has been on a 6-fight winning streak and has defended his belt 5 times since 2017 and now is ranked amongst the top 5 in the world and most importantly #1 by the WBA. A world title match against Artem Dalakian (17-0) sounds very plausible at this point and since both men have already fought this summer and have come out with no injuries, a fight between the two could take place around December.-Junto Nakatani (16-0): WBC #5 / WBO #13Undefeated Japanese flyweight prospect Junto Nakatani scored another TKO win on July 7 and now is ranked at the WBC’s top 5.-Takuya Kogawa (29-5): WBC #8After a draw with Yusuke Sakashita, Kogawa has retained his spot at the WBC rankings.-Masahiro Sakamoto (12-1): WBO #4The former WBO Asia Pacific champion will probably be in line for a WBO World title match against the winner of Kimura/Tanaka in 2019. He is scheduled to face South Korea’s Flyweight champion Ki Chang Go (6-2) on August 11.Light Flyweight:-Ryuji Hara (23-2): WBO #1Much like Ioka’s, this is the second strangest ranking, especially considering that Hara hasn’t fought since October of 2017. Actually Hara has been the #1 ranked flyweight by the WBO since January, despite having only competed once in this division against the debuting Seneey Worachina. Hara was set to face Angel Acosta for the world title on April 7 but an injury prevented him from stepping into the ring.-Tetsuya Hisada (32-9): WBA #1 / WBC #3 / WBC #6The reigning Japanese Flyweight champion, since 2016, recorded a 4th successful defense against Koki Ono (12-5) on July 16, thus improving his streak to 11 consecutive victories. Now as the #1 ranked Light Flyweight by the WBA, he is rumored to face Hekkie Budler for the gold sooner or later.-Hiroto Kyoguchi (10-0): WBA #2The undefeated IBF World Minimumweight champion has recently decided to move up a weight class and has already reached the top of the WBA ranking. If Hisada doesn’t face Budler right away, then an eliminator between Kyoguchi and Hisada looks more likely to take place.-Ryoichi Taguchi (27-3): WBC #4 / WBA #4Despite losing his 2 world title to Budler, Taguchi is still ranked amongst the top Light Flyweights in the world and without a doubt he will gain another crack at the gold in no time.

-Reiya Konishi (16-1): WBO #6 / WBA #7The former world title challenger and now new WBO Asia Pacific champion, is coming closer to once again fight for the world championship.Minimumweight:-Tsubasa Koura (13-0): WBC #3 / WBA #9 / WBO #11At only 23 years of age, Koura has already amassed 13 career wins, including 9 KOs, as well as the OPBF Minimumweight championship. His 3rd title defense will take place on August 24 against an unnamed opponent as of yet. It’s safe to say that we will see him in a WBC world title match in early 2019.-Ryuya Yamanaka (16-3): WBO #6Yamanaka recently lost the WBO world title to Vic Saludar. Just like Taguchi, he is only a few fights away from competing again for the big one.-Tatsuya Fukuhara (21-6): WBC #9Fukuhara has been victorious in both of his 2018 fights but he will need a few more before he can challenge Chayaphon Moonsri again for the WBC world title.-Shin Ono (22-9): WBO #9Ono will make his first Japanese title defense against Riku Kano (13-3) on August 24. His last world title fight was in 2016.
